Abstract

Magnetic recording device and method are provided. The magnetic recording device includes a shaping driver for positive and negative signals whose polarities are reversed, corresponding to the digital information, a push-pull portion (14) for generating a recording current corresponding to the positive and negative signals and generating a transient pulse current during reversal of the polarity of the recording current, and a current switch (12) for switching a current flowing through the push-pull portion in response to the positive and negative signals. The digital signal is recorded on the magnetic recording medium on the basis of the transient pulse current. Therefore, without an additional recording equalizer, rise characteristics of a head current is improved and the demand of small-size and low-power is satisfied. In addition, since the magnetic recording device employs a compensation signal generator (20) for compensating for a variation of the instantaneous value of a recording current caused by use of a rotary transformer, rise characteristics of the recording current during switching the polarity of the recording current can be maintained to be stable.
